But when 22-year-old Alex took a bite out of one, he found a wasp underneath the frosting.

Mrs Weightman returned to the store to complain.

She told the Nottingham Post: "We want to know if it was malicious or whether it could've just dropped down in the atmosphere.

"They need to learn from this. I do not want anybody else being made poorly from something like this."

Waitrose has apologised and is investigating the incident.

A spokeswoman said they received the complaint on September 18.

She added: "We take customer safety very seriously and are very sorry for any distress caused.

"Although this is an isolated incident, we are investigating with our branch and our suppliers how this could have happened.

"We have personally apologised to the customer and will inform her of the results of the investigation."
